Knockdown of long non‑coding RNA HCP5 suppresses the malignant behavior of retinoblastoma by sponging miR‑3619‑5p to target HDAC9

A number of studies have verified the vital effects of long non‑coding RNAs on the malignant behaviour of retinoblastoma (RB). The objective of the present study was to examine the specific role and mechanisms of HLA complex P5 (HCP5) in RB. For this purpose, reverse transcription‑quantitative polymerase chain reaction was used to determine the expression of HCP5, microRNA (miRNA/miR)‑3619‑5p and histone deacetylase 9 (HDAC9). A...
